Your numbers are very close to mine, though #4 is my hottest. I am just finishing up the wheel pants now and we'll see what that does. I ended up cutting my lower cowl exit area about 1" forward of the firewall during the first part of Phase 1, that helped quite a bit. I may end up putting it back in and installing the Anti-Splat louvers for climb cooling, we'll see.
